[Réseau Express Métropolitain] Ride on the new A4 Deux-Montagnes branch (Formerly used by EXO 6)

Experience a full ride on the new A4 Deux-Montagnes branch of Montreal’s Réseau express métropolitain (REM), which opened to revenue service on November 17 after several postponements, following open-house days on November 15 and 16. During the open house, every station on this new northwest branch between downtown and Deux-Montagnes was accessible for free rides and passport stamping.​

The video starts at Central Station (Gare Centrale) and follows the fully automated REM all the way to the North Shore terminal at Deux-Montagnes, using the converted former EXO 6 Deux-Montagnes commuter rail corridor. All former EXO 6 stations are retained, with three new stations added (McGill, Édouard-Montpetit, Côte-de-Liesse) and two stations renamed (Mont-Royal to Ville-de-Mont-Royal, Roxboro-Pierrefonds to Pierrefonds-Roxboro).​

Automation allows an unobstructed front-cab style view through the Mount Royal Tunnel and across bridges, showing the new double-tracked, grade-separated infrastructure and modern station design. All stations on this segment are fully accessible, with glass elevators throughout and escalators provided at locations with long stairways.​

Stations featured in this video: Central Station, McGill, Édouard-Montpetit, Canora, Ville-de-Mont-Royal, Côte-de-Liesse, Montpellier, Du Ruisseau, Bois-Franc, Sunnybrooke, Pierrefonds-Roxboro, Île-Bigras, Sainte-Dorothée, Grand-Moulin, and Deux-Montagnes. Future REM branches to come include A3 Anse-à-l’Orme (planned for 2026) and A2 Airport/YUL (planned for 2027), which will also be covered in full-ride videos at their commissioning.​
